In case you are unable to find discussion Meta option in your dashboard, then you have to tweak settings. There will be a “Screen option” at the top right corner of your screen, just go on that option.
There you can find so many options and between all the options you will see discussion option. Make sure the discussion option is checked and if it is not then you have to check it.
